BRAKE FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters ,Patent No. 541,983, dated July 2, 1895,

Application filed July 25, 1894.

serial No. 518,536. (No modelJ To all whom it may concern.-

Be it known that I, ROBERT L. OMEIYSETTER, a citizen of. the United States, and a resident of Philadelphia, in the county of Philadelphia 5 and State ofPennsylvania, have invented certain new and useful Improvements in Car- 'Brakes; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled 1c in the art to which it appertains to make and use the same, reference being had to the ac companying drawings, which form a part of this specification.

My invention relates to improvements in r 5 brakes for railway-cars of that class or description in which a spring-metal strip or strap is employed, which encircles a drum on the car-axle, with means for bringing said strip or strap into and out of frictional conzo tact with said drum.

The object of my invention is to provide an improved construction of the friction-drum or grooved wheel and means for connecting it with the car-wheel, whereby said drum and 25 wheel are securely connected with the axle, so as to rotate therewith, while at the same time lateral movement of the wheel and drum on the axle is prevented.

The invention consists in the novel cono struction and combination of parts hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a plan view of a car platform and truck, sh owing my improvements applied thereto. Fig. 5 2 is a central longitudinal section thereof. Fig.3 is a sectional view of the car-axle, wheel, and drum. Figs. 4. and 5 are similar views of the wheel and drum, respectively, detached.

Fig. 6 is a perspective view of one of the keys o detached. Fig. 7 is a perspective View of one end of the car-axle with the wheel and drum removed, and Fig. 8 is a detail view of the means for actuating or tightening the frictionstraps.

In the said drawings, the reference-numeral 1 designates the car-platform, consisting of longitudinal and cross beams suitably connected together. Depending from the under side of these horizontal beams are a series of 50 bars 2 with which the truck-irons 3 are connected, said bars being encircled by coiled springs 4 for taking up the jolt of the cars.

The numeral 5 denotes the axle-boxes, which, as well as the truck-irons, may be of any ordinary or suitable construction.

The numeral 6 designates the car-axle, liavdrum, having an aperture 16 and a groove 17, similar to groove l t in the wheel. In connecting the wheel and axle together the drum is first placed upon the axle and the key inserted in the groove, fitting snugly therein. The wheel 12 is then placed upon the axle and driven home, so that the outer end of the key and the contact-rib 10 will fit in the grooves 14 and 13, respectively. The drum is now pushed flush up against the'inner face of the wheel, the outer end of the key engaging with the groove 17 therein, and the wheel and drum are secured together by bolts 18, passing through registering apertures. Bythis means the wheel and drum are firmly connected with the axle, so as to rotate therewith, and the wheels cannot be removed until disconnected from the drum or disk.

The numeral 21 denotes a transverse beam secured to the truck-irons and provided with upwardly-extending brackets 23, which, in connection with the truck-irons, support short bars 24, carrying bearings 25, in which is journaled. at each side of the platform, a lever 26, one arm of which is connected with the oppositely-extending rods 27, which in turn are connected to spring-metal friction-straps 28, part-1y encircling the friction-drum ofthe axles. The other ends of these straps are adjustably connected with some fixed part of the platform or trucks.

It will be noted that there are two drums and brake-straps on each axle, and the rods 27 at each end of the car are connected together by a transverse rod 29, provided with an operating-lever 30, so that all the brakes may be operated simultaneously from either end of the car.

While my invention is designed primarily for use in connection with strap-brakes for railway-cars for connecting the friction-drum with the Wheel, yet it is obvious that it may be employed independent of the brake mechanism for connecting car-Wheels to axles. In this case I may use a disk or plate in place of the drum or grooved Wheel Without affecting the principle of the invention.

, Having thus described my invention, What I claim is The combination with a car axle having a horizontal groove therein, the key consisting of a rectangular plate having a projecting rib, seated in said groove and projecting, beyond the surface of the axle, the car Wheel having the intersecting grooves, adapted to engage with the outer end of said key and with the rib thereof, the drum or disk having a groove engaging with" the inner end of said key, and the securing bolts, substantially as described.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two Witnesses. v
